* Bus Enumeration by Freescale PCI-X Agent
|
||
|
|
|
||
|
|
Typically any Freescale PCI-X bridge hardware strapped into Agent mode
|
||
|
|
is prevented from enumerating the bus. The PrPMC form-factor requires
|
||
|
|
all mezzanines to be PCI-X Agents, but one per system may still
|
||
|
|
enumerate the bus.
|
||
|
|
|
||
|
|
The property defined below will allow a PCI-X bridge to be used for bus
|
||
|
|
enumeration despite being strapped into Agent mode.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- fsl,pci-agent-force-enum : There is no value associated with this
|
||
|
|
property. The property itself is treated as a boolean.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
/* PCI-X bridge known to be PrPMC Monarch */
|
||
|
|
pci0: pci@ef008000 {
|
||
|
|
fsl,pci-agent-force-enum;
|
||
|
|
#interrupt-cells = <1>;
|
||
|
|
#size-cells = <2>;
|
||
|
|
#address-cells = <3>;
|
||
